Basic image cell in contact-type multiview three-dimensional imaging systems

Abstract

The viewing zone of a contact-type multiview three-dimensional imaging system are divided into nine viewing regions by assuming that at least n - 2 pixel cells can be viewed at each of the regions, where n is the total number of pixel cells in horizontal direction of a display panel. Each of these regions consists of m(2) subregions, where m is the number of pixels in the horizontal of a pixel cell. The image viewed at each of the subregions reveals a disparity of 1 pixel distance with that viewed at its adjacent subregion. Hence, each subregion is defined as a basic image cell that can provide the disparity of a pixel distance with its immediate neighbors. The width of the cell is independent of the focal length of the viewing zone forming optics but highly sensitive to the pixel size. It can be smaller than viewers' pupil sizes by decreasing the pixel size. (C) 2013 Society of Photo-Optical Instrumentation Engineers (SPIE)
